Erdős number is named after Paul Erdős, a Hungarian mathematician who published more than 1,500 papers with 511 collaborators. Erdős number describes the "collaborative distance" between a person and Paul Erdős, as measured by co-authorship. Paul Erdős himself has the Erdős number of 0. A person has the Erdős number of k+1 if k is the lowest Erdős number of all of his co-authors.
My Erdős number is 4, which is achieved by the following two different paths (no common nodes except at the ends of the paths):
